Attachment: One-click update to 0.5 fails
This is a known issue (see Changelog). The automated update was inadvertently broken in 0.4.4 and 0.4.5. If you are running either of these versions, please update manually to 0.5 (see How to update Piwik manually?), preferably by installing Piwik in a fresh folder. Our apologies for the inconvenience.
